Weighing just 1.61 lbs, it balances strong anti-theft protection with portability, featuring a hardened locking pin and a cylinder resistant to picking and drilling. Ideal for low to moderate crime areas, it includes two keys, qualifies for Kryptonite’s Anti-Theft Protection Offer, and comes with a limited lifetime warranty for lasting reliability. ## Description The Kryptonite Keeper Integrated Chain features 5mm four sided chain links made from hardened carbon steel. Includes a durable weather-resistant nylon sleeve to prevent scratches. Recommended for use in low crime areas. Review: Stong, durable, not too heavy. - This is a durable and strong lock, with plenty of flexibility to be used in a variety of ways. I was able to buy a second set of keys for safe keeping. Review: easy to carry and use - I appreciate other reviews that mentioned weight and bulk. I had been considering the Keeper 785, but the 585 weighs less than half as much (3.5 vs 1.61 lbs.) and is noticeably less bulky, making a very tidy fit wrapped around my seatpost. Kryptonite's scale of 10 security ratings puts the 585 at 4 and the 785 at 5, so both are in the 4-6 range that their application chart says is suitable for my rural/suburban stops of up to 2 hours. For a lubricant, Kryptonite recommends the same Finish Line Dry product my dealer told me to use on the bike chain, and the lock style is quick and easy to use. I'm very pleased with this convenient deterrent to casual theft while out and about on my bike. Update: After 16 months of use, and I'm out on my bike and using it 4-5 days per week throughout the entire year, everything continues to look great and operate smoothly and easily. Extremely satisfied with this purchase. ## Features - 5mm FOUR-SIDED CHAIN LINKS: Made from hardened carbon steel provides excellent resistance against cutting and leverage attacks - HARDENED LOCKING PIN & SECURE CYLINDER: Features a hardened locking pin for extra holding power and a wafer-style cylinder that resists picking and drilling for enhanced security - PROTECTIVE FEATURES: Durable rubber coating around helps prevent scratching and wear and tear on your bike.

This is my second one where the key stays inside the chamber when the lock is unlocked.** A: No. You have to unlock and then remove key **Q: One of my keys have been misplaced. How can i get a copy of it?** A: Contact Kryptonite directly and be ready to give them the S/N on the lock **Q: Key lock verses digital code locks?** A: I only use bike locks once in a while and typically for short periods of time. Like a quick stop for lunch. For this application I like keys. I tend to lose track of combinations over time. Especially when they are hanging in my basement for a year or more. Keys stay in the lock when not being used so I don't have to have a system for keeping track of combinations. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Stong, durable, not too heavy. *by M***E on September 24, 2025* This is a durable and strong lock, with plenty of flexibility to be used in a variety of ways.
